影響電伴熱(re)(re)帶系統熱(re)(re)損失(shi)(shi)的(de)(de)(de)主要(yao)因素 周圍環境溫(wen)度(du)(du)(du)(du) 周圍環境溫(wen)度(du)(du)(du)(du)的(de)(de)(de)變化對(dui)于介質熱(re)(re)量(liang)(liang)的(de)(de)(de)損失(shi)(shi)影響也是(shi)較(jiao)大(da)的(de)(de)(de)，環境溫(wen)度(du)(du)(du)(du)越低(di)，其熱(re)(re)損失(shi)(shi)就越大(da)。為了(le)保險起見，我(wo)們往往估計較(jiao)低(di)，這樣計算的(de)(de)(de)熱(re)(re)量(liang)(liang)損失(shi)(shi)就會偏(pian)大(da)，導(dao)致選用更大(da)功率的(de)(de)(de)電伴熱(re)(re)帶產品。所以，在確認較(jiao)低(di)的(de)(de)(de)環境溫(wen)度(du)(du)(du)(du)是(shi)要(yao)合(he)理(li)，另外(wai)風速對(dui)熱(re)(re)量(liang)(liang)的(de)(de)(de)散(san)失(shi)(shi)也有影響，風速越大(da)熱(re)(re)量(liang)(liang)的(de)(de)(de)散(san)失(shi)(shi)也越大(da)。 較(jiao)大(da)承載(zai)(zai)溫(wen)度(du)(du)(du)(du) 有時設(she)備或(huo)者(zhe)管(guan)道(dao)(dao)(dao)的(de)(de)(de)工藝溫(wen)度(du)(du)(du)(du)并不高，但是(shi)在特殊的(de)(de)(de)情況(kuang)時可(ke)能引人更高溫(wen)度(du)(du)(du)(du)的(de)(de)(de)介質。例如：一(yi)條管(guan)道(dao)(dao)(dao)，正常(chang)時的(de)(de)(de)溫(wen)度(du)(du)(du)(du)僅有幾十攝氏(shi)度(du)(du)(du)(du)，但該(gai)管(guan)道(dao)(dao)(dao)需要(yao)用蒸(zheng)汽進行吹掃，蒸(zheng)汽的(de)(de)(de)溫(wen)度(du)(du)(du)(du)可(ke)能達到(dao)200攝氏(shi)度(du)(du)(du)(du)。這就要(yao)求(qiu)(qiu)伴熱(re)(re)產品的(de)(de)(de)較(jiao)大(da)承載(zai)(zai)溫(wen)度(du)(du)(du)(du)要(yao)達到(dao)200℃，否(fou)則可(ke)能造成伴熱(re)(re)產品的(de)(de)(de)損壞。所以說不僅要(yao)考慮介質的(de)(de)(de)需求(qiu)(qiu)維持溫(wen)度(du)(du)(du)(du)，也要(yao)考慮到(dao)較(jiao)高耐(nai)溫(wen)需求(qiu)(qiu)。

電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)等于電(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)嗎？ 電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)并不等于電(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)。 在(zai)生產(chan)(chan)中，因為(wei)秋冬溫(wen)(wen)度(du)低(di)，生產(chan)(chan)中管線介質的(de)(de)(de)溫(wen)(wen)度(du)會(hui)(hui)隨之降(jiang)低(di)，導致生產(chan)(chan)裝(zhuang)置(zhi)無法生產(chan)(chan)合格的(de)(de)(de)產(chan)(chan)品。很(hen)多企(qi)業都會(hui)(hui)選擇電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)系(xi)統(tong)(tong)作(zuo)為(wei)管道熱(re)(re)(re)(re)(re)補償的(de)(de)(de)裝(zhuang)置(zhi)，甚(shen)(shen)至會(hui)(hui)為(wei)了提(ti)高生產(chan)(chan)效(xiao)率而擅(shan)自拆(chai)除保(bao)護(hu)器，提(ti)高電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)系(xi)統(tong)(tong)的(de)(de)(de)伴(ban)(ban)熱(re)(re)(re)(re)(re)溫(wen)(wen)度(du)。電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)不等于電(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)，擅(shan)自拆(chai)除保(bao)護(hu)器等裝(zhuang)置(zhi)，不顧輸出效(xiao)率地提(ti)高電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)的(de)(de)(de)加(jia)(jia)熱(re)(re)(re)(re)(re)溫(wen)(wen)度(du)，后果非常危(wei)險。 在(zai)生產(chan)(chan)中，如果將電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)當做電(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)來使用，隨意(yi)提(ti)高電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)系(xi)統(tong)(tong)的(de)(de)(de)溫(wen)(wen)度(du)，而且(qie)是長時(shi)間(jian)(jian)運(yun)行(xing)(xing)，雖然在(zai)短時(shi)間(jian)(jian)內可以提(ti)高生產(chan)(chan)效(xiao)率，但并不利(li)于電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)系(xi)統(tong)(tong)的(de)(de)(de)使用和維護(hu)。電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)系(xi)統(tong)(tong)長時(shi)間(jian)(jian)高溫(wen)(wen)度(du)運(yun)行(xing)(xing)容易出現(xian)燒斷、損毀電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶，甚(shen)(shen)至引發火災的(de)(de)(de)情況，
